Re: [Jython-dev] developing an IDE for jython

[Yaqiang W. <yaq...@gm...>]

Also a Jython editor (IDE) was developed in MeteoInfo (
https://github.com/meteoinfo/MeteoInfo) project names MeteoInfoLab for
scientific computation and plotting. For better using by others, I recently
is pealing several projects from it. For example: NumJy (
https://github.com/Yaqiang/numjy) for multi-dimensional array operation and
computation, PlotJy (https://github.com/Yaqiang/plotjy) for 2D/3D plotting,
and EditorJy (https://github.com/Yaqiang/editorjy) for Jython code editing
and running. I noticed that Fiji script editor also use Rsyntaxtextarea,
which is a good base to learn the experience from Fiji project.
